Mumbai the capital of Maharashtra is also the financial capital and the most populated city of India.

Mumbai has grown in recent decades for many residential and commercial developments.

Diminishing of Industrial zones and development of corporate offices, mall culture in very short

period is one of the features of today’s Mumbai.

The Mumbai has many old, dilapidated structures. They are very unsafe to retain. Many of them are

in CRZ zones. Development of those by rehabilitant those tenants along with development of new

flats to compensate the development charges will not be possible if extra FSI is not used. Because of

CRZ conditions the FSI restriction makes those structures unattended.

But because of New CRZ notification 2011, it is possible to compensate development charges by

developing these structures. The one of such project of unsafe, dilapidated building of residential use

as declared dilapidated structure by office of P Ward is discussed here.

Parameter

ENVIRONMENTAL CONCERNS

4.1 AIR POLLUTION

1] Source: - The source of Air Emissions is from the use of some equipment like concrete pumps,

mixers, etc. These equipments consume Diesel as fuel during their operation. Carbon Monoxide,

Hydrocarbons, Oxides of Nitrogen and Particulate Matter etc. will be the major pollutants.

Fugitive Emissions i.e. Emissions from construction activities will mainly consist of dust. Movement

of Heavy & light vehicles, for loading and unloading of Construction Materials, transporting people,

will also add on to source of emissions.

equipments with regular maintenance.

4.3 WATER POLLUTION

1] Use : - The MCGM water will be used for domestic purpose i.e. drinking water for staff and

laborers working on the field whereas bore well water/Tanker water will be used for various

constructions activities like, Concreting, Plastering , Flooring & Finishing etc.

2] Effluent : - There will be no generation of effluent from construction activities as the water used

for concreting; Plastering, Flooring and Finishing etc. will get evaporated during drying or curing



time. All the construction activities are physical in nature. The Domestic Effluent will be generated

due to the persons working on the site who will require water for drinking, cleaning, bathing etc.

Sullage generated during operation phase will amount to 44.97 CMD which will be treated in the

Grey Water Treatment Plant. The treated water will be used for non domestic purposes such as

gardening, car washing, flushing etc.

3] Treatment & Disposal:-The Domestic Effluent generated in construction phase will be disposed

off in existing MCGM Sewer.

4] Rain Water Harvesting: The plot is already covered with dilapidated existing one building

structures of Ground + 3 upper floors structure occupying 32 existing tenants/ occupants. The same

will be developed in Basement + Ground + 1st to 20th

• Percolation Pits: 4no. (0.5 * 0.5 * 2m)

Upper Floor for Residential Building. The plot

area is 1198.01 sq mtrs. Roof top rain water harvesting is proposed in the project. The permeable

paver blocks are proposed along with 4 Recharge pit to increase the percolation of rain water into the

soil rather than flowing to the drain.

* (AS PER MOEF GUIDELINES)



5] Storm Water Discharge:

Storm water drains will be constructed for proposed facility as per the norms. The Rain water

recharge pits will help to reduce the runoff and reduce the load on external storm water drain.

3] Control of Emission: - Proper precaution will be taken to reduce the particulate matter by water

sprinkling on the dry site area, barricading the periphery by corrugated tin Sheets of 5.0 mtrs height to

protect the surrounding area from dusting. The pollution generated will be controlled by, allowing

vehicles that will comply to mass Emission Standard (Bharat Stage –II) stipulated by Central

Pollution Control Board (CPCB)–Ministry of Environment & forest (MoEF), New Delhi. Also it will



be ensured that the vehicles will carry PUC certificate. To minimize air pollution efforts shall be

made by use of equipments, which area electric power driven.

4.6 SOLID WASTE MANANGMENT DURING OPERATIONAL PHASE

1] The project proponents have proposed provision for segregation and collection of biodegradable

& non-biodegradable waste within the premises.

2] Solid transfer stations have been proposed for collection, sorting, segregation, storage &

transportation of biodegradable and non-biodegradable waste.

CALCULATION FOR QUANTUM OF SOLID WASTE TO BE GENERATED IN THE

BUILDING DURING OPERTAIONAL PHASE:

• Total no of persons = 722 persons

• Generation of Total waste per person = 500 grams/day (as per Solid waste management study

– Year - 2005 conducted by NEERI)

• Total solid waste generation will be 722 x 500 gms/person/day = 361.00 Kg

• Generation of organic waste = 30.84% of total waste (ref. Table 2 in next page)

• So total organic waste generated by the occupants = 361 x 0.3084 grams = 111.33 kg by all

occupants of the building.

• We will provide one bins of each capacity 5 kg at every landing.

• Dry waste will be collected separately in wheeled bins as required as per MCGM guideline

and transported to common collection area by MCGM.

• E-waste :Shall be stored separately and disposed of to the recyclers authorized by MPCB
